    Hi There,

    Your videos on Amla have been fascinating and I’d like to give some a try. However, I’ve long been aware that food and natural medicine products from China and India are generally not to be trusted due to contamination from heavy metals and who knows what else.

    How confident can you be to go to an Indian food store and purchase Amla powder? Would it not be just as potentially contaminated with heavy metals as the Ayurvedic medicines were in the study featured in this video?

    Also, what would be a safe dosage and at the same time useful dosage of Amla powder?


    • P.C. Patnaik

      Very reputed Ayurvedic manufacturers like Zandu, Dabur, Baidyanath, Hamdard etc. have gained trust of Indian masses for centuries. Their products are subjected to Indian Government strict quality verifications. Had your suspicion been correct, then these companies could NOTm withstood the test of time.

      • Muhammad Tatarstan

        Hamdard – it is Unani medicine company (not Ayurvedic).
        Zandu, Dabur – not best choice. Not “very reputed”.
        Dabur may add supplements preservatives like Sodium Benzoate to jam (chyavanprash), methylparaben, methylparaben e.t.c.
        It’s not real (traditional) Ayurveda

        Very reputed Ayurvedic manufacturers are : AVS, AVN, AVP, SNA, Vaidyaratnam Oushadhasala, Nagarjuna e.t.c (manufacturers mainly from Kerala)

    Does anyone have any information on contamination in ashwagandha root powder? I read an article that it increases glutathione, SOD, and catalase levels as well as being excellent for anxiety and is taken in India as a general tonic. But if it has lead, mercury or arsenic, it might be doing me more harm than good.

      From experience, it seems that ashwagandha is not good for those with psoriasis. Perhaps it perks up energy and it is not the kind that someone with an auto immune disease needs. I thought it was worth a try and then broke out in psoriasis. I researched that auto immune diseases should avoid ashwagandha as well as cinnamon.

    Dr. Greger,

    Per the previous comment, how can we be assured that Amla purchased here in the U.S. is heavy metal free?

    Please advise…

  • LouiseF

    this video is confusing. So do we use it or not?

    • jkearns97062

      This is not an endorsement, but one source, Banyan Botanicals, says that their products are USDA Organic and says they test for Microbiologicals, Heavy Metals, Pesticides, and Identification. They say they are “fully compliant with the USDA’s National Organic Program, ANSI Standard 173, AHPA standards and the new cGMP for Dietary Supplements.” They list their Quality Control info here:

      What do you think, Dr. Gregor? Thanks!

  • BettinaC

    For those worried about contamination issues with these herbs, I highly recommend purchasing organic versions of them online from Mountain Rose Herbs (, a bulk herb and spice supplier with a long history and good reputation for quality. (No, I don’t have any affiliation with them other than to be a happy customer :-) They sell organic amla and triphala powder as well for those who, like me, have been excitedly following Dr. Greger’s videos and want to rush out and buy some.

    • TMR

      Thanks for this :)

  • Veguyan

    At Mountain Rose Herbs they still tout Amla as having tons of Vitamin C. I thought I saw on this site Dr. Greger dispelling the belief that Amla has Vit. C.

    • Michael Greger M.D.

      Nope–packed with C!

  • galactus617

    Wow. I was so excited, I went out to buy amla last night. Now I am concerned regarding the safety of the product.

    • Michael Greger M.D.

      Stay tuned–we’re not at the end of the story yet (and it has a happy ending! :)

      • galactus617

        Thanks Doctor.

        I would like to use a safe form if amla. I bought a few different versions of it. Frozen. Sweet/dried. I also tried. Chyawanprash. Is that also good for you. It says it is mostly amla. Just wondering if you had a point of view on this. I am looking forward to your next post.

    • egel egel

      Buy organic amala ..this is US branding that synthetic vitamin supplements are better than natural one

  • lazarito
  • anniekcr

    Dr. Greger, where do you obtain the amla you use in your smoothies?

    • Michael Greger M.D.

      I have an Indian spice store in my neighborhood I go to, but I’ve found it in a few other such stores around town (near DC where I live).

      • Katybcmt

        How do you know from which store you can buy Amla? Do you have any guidelines? Can we trust the online stores that say it is organic?

        • Toxins

           Typically, if you visit a local Indian store, they will sell various forms of Amla. From powdered, frozen and dried. I personally prefer powdered.

      • Lucia13

        I get all my Ayurvedic products from do you have any idea if their products are safe?

  • Gary Yuen

    Amla is a fruit grouped together with other foods, herbs and spices. “The agents which cure body and mental diseases, delay old age, increase mental power, generating power, vital energy, eyesight, impart intelligence, memory, aid proper digestion and clear complexion are Rasayana.”

    Chyawanprash is a tonic that’s made from dozens of substances. I think the story goes one elderly fellow married a young woman and so asked for an elixor to restore his vitality. It’s commonly used in India by the general popuation during winter to maintain immunity — perhaps only a side effect of marketing. But it’s main purpose is immunity.

    There are several main Indian ayurvedic companies you can find here such as Dabur, Himalaya, and Sandhu. I tend to use those companies (since I can find them). I’m not sure if the studies of metal findings list which formulations in which they were found. If mercury was in something particular, it should be because the formula asks for it. I have heard of it’s use but don’t know much about it since I don’t “practice” ayurveda and none of the books in English (I’ve found) talk much about it. If metals were found in pure herbs or triphala, perhaps it is because of like what you see with soy warnings (this product made in a facility that …). Not sure if this is really common.

    I also use Banyan Botanicals (like for triphala) for the herbs I use more regularly (and that they offer). They say organic so I’d guess it probably is. There isn’t much else out there (from US companies) anyway. As far as safety of Indian companies, I have talked (only a bit but not in detail) to doctors that say bigger companies should be safe since they’re tested. But who knows. For Chyawanprash, I have heard of one tests of different brands in an Indian magazine. Am trying to ask someone for a copy of that. And will try to find out more.

    • cin3

      thanks Gary

  • liz LaRue

    Wow. Thank you. Unfortunately, I just ordered some amla online (organic- but who knows?)
    Do you have a brand or source to recommend for these herbs. Amla and triphala in particular? I have a friend just diagnosed with stage 4 pancreatic cancer and want to suggest the triphala. Thank you, Liz.

  • mapiceo

    Any products coming from the 3rd world should be tested. We test all our products twice for heavy metals and live organisms. We are completely transparent with all test results and meet all APHA standards. Alan Marks, CEO, Maharishi Ayurveda Products Int.

    • Southbaysteve

      LOVE your organic Amla tablets. I use it often and I am going to continue (I also take organic ground fenugreek seeds, curcumin and a couple others). Is the MAPI Amla berry US grown? Thanks again!

      Dr. Greger, as always, OUTSTANDING reporting. You are amazing.

      • mapiceo

        SouthBay. The amla is sourced and manufactured in India. It is tested in labs in India and then again when it arrives in the US. We are happy to share test results. Additionally, our amla is made according to the ancient texts. Is it not just dried and ground, rather is is produced using a 21 step process.

  • Tom Bohman

    I wasn’t aware of ayurveda as a brand of medicinal foodstuff, but as ‘life science’, an analytical device to bring health and balance not only to people but to the environment. Seems to me the use of the term “Ayurveda” has been misused in this video. Don’t you think?

  • MelanieP

    Ghee seems to be popular in Ayurvedic medicine…lots of claims of
    health benefits. Isn’t it just a slightly different version of butter?
    Would love to see a video about it’s downsides (since all I seem to find
    are articles by proponents of it).

  • P.C. Patnaik

    If report says that one in five Triphala preparations contains dreaded chemicals like Arsenic / Lead / Mercury, then how one Indian wiull consume this nectar of God, safely ? What is the brand name of manufacturers in India whose preparatiosn are really safe ?

  • Marie

    How do I know if the Amla powder I have contains toxic metals? Is there a home test kit I can use?

    • Toxins

      This video will benefit you.
      Amla tested and found to not contain toxic metals.

    • Satyendra

      Well you guys are very much confused by the Doctors in the US who are driven by the Pharma Companies (Insurance huh in US and compare it with Indian system). My Father is also suffereing with severe Grade 3 Cirrhosis with Acute Ascitis and Bleeding PHG. But he is still on Ayurvedic supplements and able to survive for yet another days since last 2 years.

      Well, I agree that some of the Ayurvedic products have heavy-metals and they intentionally add them. These Products have to be given only in rarest and critical condition when no primary secondary or tertiary level medicines work.

      Do we remember Zinc (Yashad Bhasma)! When ‘West’ used to say it is lethal but not Copper and Zinc Supplements are proven to be effective.

      Similarly Mica (which is slightly Poisonous) is used in Ayurveda. For one disease there are various paths in Ayurveda. It is upto you to demand the Heavy-metal free pathway for the treatment.
      Borax which is also called Tankan is excellent Anbiotic and Anti-Aging for applying ointments etc. I have been using the ointments and oral pills multiple times since my childhood and found to be perfect.

      Do you guys know that some of the Allopathic system have the Hormonal Medicines which are manufactured using Human/Hares Urine. In Indian distilled (Please read it again as Distilled) urine has been used in ayurvedic system to heal the metobolism.

      And RadioActive Barium, why it is used by the Doctors??
      Why do you consume Pottasium Chloride in Soups, Noodles and Chineese Continental items?
      Why MSGs and MSG-likes are added for tastes?

      So, the final solution is to have get the disease diagnosed with the best Ayurvedic Practitioner, ask him/her to offer the standard and best medicines of brands like Dabur, Baidhyanath, Sandu or Zhandu and follow the strict dietery restrictions and guidelinesas per your Doctor or Ayurvedic Practitioner.

      But please do not fell into any trap just by any MD/MS Doctors. They could be good in their profession but not always. Allopathic is best in its scope and so as Ayurveda and practitioners in both of them should not be sought for their mixed-advices.

      At the end, I hope everyone in this world should get the peaceful social life without any physiological problems. Use your senses and get the problem solved and diseases cured, be it get done by Allopathic or Ayurvedic. And, spread the magical experience all across your stretch.

      Dhanyawad and Om Shanti OM

  • Zambanini4Equality

    It would be nice to know which brands to avoid and which ones to buy! Has anyone studied this – or dared to publish the brand names of the toxic triphala products? It seems this should be the law! Are these product brand names mentioned in the actual study but not mentioned in the video? If so could you please do a new video mentioning the brand names to be avoided. Is the problem completely avoided by buying organic Triphala products? Or are there some organic brands that are still contaminated with heavy metals?

  • R. Martinez

    How about ashwagandha? I read it helps anxiety, and lots of other conditions. Is it safe?

    • egel egel

      Ashwaganda is stimulant its doesn’t cures it from organic india

  • jaden

    have you looked into mike adams’ research on the heavy metal retention factor? essentially what they’ve found is whole foods actually retain toxins in the fiber structure so that they are not absorbed into the body. different plants retain different amounts of different things, but just because the lead is found in the plant doesn’t mean its being absorbed into the body

  • Jean-Marie Vallet

    I am looking for an herbal treatment for addressing non stop, high pitch bilateral, peripheral tinnitus, most likely related to stress/ cortisol/ kidney/liver. Thank you.

  • ufoo

    The title is a bit misleading “some ayurvedic medicine worse than lead paint exposure” It is not the medicines that are worse (as the title suggests). It is that some companies’ preparations have poisonous additives like lead.

  • anon

    Of course the CDC is going to refute natural treatments! Natural treatments make them NO money; always always follow the money trail. They say pesticides are dangerous when it comes to natural supplements, and yet GMO foods laden with pesticides are “safe” according to the CDC and FDA. Come on, this type of information where the people have a financial interest, is completely false.

  • Eli

    Banyan Botanicals has an extensive range of Ayurvedic herbs, all tested for contaminants. It’s based in New Mexico so it has to comply with US manufacturing guidelines, as well as doing voluntary testing. Highly recommended–they’re nice people, too.
